HEEL-SEAT-FITTING- MACHINE.

Application filed August 24, 1917.

'10 all w/mmwiz may concern:

Be it known that l, DERwIN \V. BOWIE, a citizen of the United States.residing at. \Voodridge, in the county of Bergen and State of NewJersey, have invented certain Improvements in Heel-Seat-FittingMachines, of which the following description, in connection with theaccompanying drawings, is a specification, like reference characters onthe drawings indicating like parts in the several figures.

This invention relates to a machine for shaping the heel end of a soleto prepare it to receive the heel which is to be attached.

In the manufacture of shoes having leather heels it is customary toattach the rough heel, then to trim the heel and the edge of the heelportion of the sole simultaneously and later to scour and burnish them.lVith wooden heels, this procedure has not been found to be practicablesince to trim a wooden heel and the edge of a leather solesimultaneously in a satisfactory manner is difficult if not impossible.Moreover a wooden heel is commonly covered with a thin veneer of leatherwhich can not be subjected to the scouring operationwithout injury.Accordingly it is thepractice to finish wooden heels completely beforethey are attached and to trim off the edge of the heel portion of thesole of the shoe so as to permit the upper edge of the heel to ex tendclose to the upper of the shoe.

These wooden heels have a cavity in their upper face; and the trimmingof the heel portion of the sole should be such as to provide a seat toreceive this cavity. Hitherto this operation has been performed by handor by machines like that of United States Letters Patent No. 1,307,285,granted June 17, 1919, on an application filed Sept. 14, 1915, in whichthe work is held stationary while traveling cutters form the heel-seat,such machines having proved accurate and satisfactory.

A general object of the present invention is to provide a simplermachine for use in forming heel-seats. I To this end one feature of theinvention comprises a cutter and means for relatively guiding the workand the cutter to cause the cutter to traverse the periphery of the heelend of the sole to remove waste stock therefrom in such a manner as toform a generally convex seat.

Serial No. 188,003.

In the illustrative machine the shoe with the sole attached issupported. guided and turned by hand, this operation being facilitatedby a novelgage or other guiding mem her while a rotary cutter removes ahorseshoe-shaped portion from the margin of the heel part of the sole toform a seat for the heel.

This and other features of the invention. including the form of the andother details of construction and combinations of parts, will bedescribed as embodied in an illustrative machine and will be pointed outin the appended claims.

Referring now to the accompanying draw- 1ngs,

Fig. 1 is an end elevation of a machine in which the present inventionis embodied;

Fig. 2 is a front elevation of the machine;

Fig. 3 is a perspective of a portion of a shoe showing the heel seatwhich is formed by the beveled cutter, and

Fig. 4 is a similar perspective showing the offsets which are formed bythe milling cutters.

Rotatably mounted in bearings in the frame of the machine are two shafts5 and 7, the shaft-5 being driven by a belt 9 and the shaft 7 beingdriven from the shaft 5 by a belt 1'1. Fast to the end of the shaft 5 isan end cutter l3; herein shown as of frusto-conical shape, andco-operating with this cutter is a guiding member 1? herein shown as agage or rest the purpose of which is to facilitate relatively guidingand turning the work and the cutter 13. I The gage 17 comprises a narrowplate having a beveled lower end adapted to enter the rand crease of ashoe and provided at its upper end with a transverse slot 19 to receivea disk 21 carried at the lower end of an ad justing screw 23. A screwbolt 25, which passes through a slot in the and is threaded into the arm27 which carries the thumb screw 23, serves to hold the gagefirmlytached to the shoe; and in the operation ol the machine, as thusfardescribed, the rand crease is presented to the gage 17 at one end ofthe line where the breast of the heel when attached will join the sole.The shoe is then moved along and turned until the opposite end of theline of the heel breast has been reached. During this moving and turningthe cutter 13 removes stock in a horseshoe-shaped area from the heelportion of the sole with the result illustrated in Fig. 3. In Fig. 1 oneof the positions occupied by the shoe during the cutting operation isindicated in dotted lines. It should be noted that the cut extends fromsubstantially the line of junction of the upper with the sole to a linelocated a suffici'cnt distance inside said line of junction to provide abeveled seat for the heel which is to be attached.

It is usually desirable to produce sharp ofi'sets or shoulders at theends of the horseshoe-shaped cut to provide abutnients for the upperforward corners of a wooden heel. To this end there are mounted on theshaft one at each end, milling cutters 33, and adj acent to each millingcutter is a gage or rest 35. The purpose of providing two millingcutters is first to cause the cutting to be done from the outside intoward the middle portion of the sole and second to provide'space forthe fore-part of the shoe during the cutting operation. It is obvious,

however, that a single cutter could be used for cutting both shouldersif desired instead of using two cutters, one for the right and one forthe left side as shown. The gages 35 are vertically adjustable by meansof thumb screws 37 in sockets in the two approximately upright arms of aforked bell crank lever 39 which is pivoted to the frame of the machineat 41 and is normally held. up by a spring 43 but may be pulled down soas to turn it in a counter-clockwise direction about the pivot 41 bydepressing a treadle (not shown) which is attached to the lower end ofthe treadle rod 45.- The is presented, as indicated in dotted lines in-Figs. 1 and 2, first to one milling cutter and then to the other, thetreadle being manipulated to position the gages so that cuts of thedesired depth will be made. The above described shoulder cutting meansis not claimed herein, as it forms the subject-matter of my divisionalapplication Serial No. 572,417, filed July 3, 1922.

Although the invention has been setforthas embodied. in a particularmachine, it should be understood that the invention is not limited inthe scope of its application to the particular machine which has beenshown and described Having thus described my invention, what I claim asnew and desire to secure by Letters Patent of the United States is:
